Solar 6220-1A Audio Isolation Transformer

The Solar 6220-1A Audio Isolation Transformer is tailored for screen room testing, meeting MIL-STD-461/462 and other EMI standards. It can measure low-frequency EMI currents more effectively than standard probes and functions as an isolating inductor for transient tests. Handling up to 200 watts over 30 Hz to 250 KHz, and up to 50 A of AC or DC, it features a two-to-one step down in its secondary winding, combining efficiency with a range of capabilities.
